- WHICH IS THE unbraced length "L" TO CONSIDER, ACCORDING TO SECTION 4.5.4.2., FOR TUBULAR POLE STRUCTURES WHERE SECTIONS DIFFER IN DIAMETER AND/OR THICKNESS
Section 4.5.4.2 is intended to be applied to latticed tower members. Unbraced length does not enter into the calculations of ... - Where it has been suggested in previous posts that topography factors shall be determined in the worst case wind direction. Can the combination of topography factors and exposure factors in specific wind directions be looked at differently for each wind direction or must the worst case topography and worst case exposure apply in all wind directions?
One Exposure Category is to be used for all directions per Section 2.6.5.1. The topographic factor can be direction dependent ... - We understand section 2.6.4.1 to apply only to areas that are not listed in App. B or to areas that may have special wind or ice loading that generate higher loads than those specified in App. B. Would it be possible to use section 2.6.4.1 to justify wind or ice loads that are less than those prescribed in App. B?
The basic wind speeds recently published within ASCE7-10 may be used. Refer to FAQ ID Number 1110. Basic wind ... - Waveguides, downleads, and other cables are frequently strapped to tower legs. Sometimes there is just one, sometimes there are many. Sometimes they're just on one leg, sometimes on all. TIA-222-G section 2.6.9.1.1 note 5 provides guidance for attachments such as step bolts and "similar linear irregularities" on round structural members. Is "similar linear irregularities" intended to cover linear cylindrical objects strapped to tower legs, even though (it seems to me) that they are not at all similar to step bolts and that they will affect wind drag on a tower in a different way than step bolts? If the answer is no, then what section of 222-G deals with this? If this is not in 222-G, then how are one or more linear cylindrical objects strapped to one or more legs supposed to be treated?
Section 2.6.9.1.1, Note 5) addresses the roughness of a round member (i.e. a tower leg) and the increase in wind loading ... - Which of the states adhere to the Rev G standard ?
